Lund High-Power Laser Facility @ LLC

The Lund high-power laser facility, founded in 1992, is one of the leading facilities in Europe for high-intensity laser-matter interactions, attosecond science and short-wavelength laser spectroscopy. Being a spearhead of the Lund Laser Centre, which is a European Major Research Infrastructure, this Facility is open not only to Swedish scien­tists, but also to scientists from the rest of Europe.

Key laser systems
